Figure 1 Flow diagrams for the trials. BMI: Body mass index; GFR: Glomerular filtration rate.

Figure 2 Number of times Richmond Agitation Sedation Scale scores in and out the target range. A: Dexmedetomidine group; B: Propofol group. RASS: Richmond Agitation Sedation Scale scores.

Figure 3 Dynamic changes of serum S100-β and neuron-specific enolase levels in patients with mechanical ventilation. A: S100-β; B: Neuron-specific enolase. NSE: Neuron-specific enolase; NS: Not significant. ^aP < 0.05; ^bP < 0.01; ^cP < 0.001.
